STOCK-FEEDING-TANK HEATER.

Specification of Letters Patent.

Patented Apr. 19, 19121.

Application filed November 26, 1920. Serial No. 426,539.

To all whom it may concern:

Be it known that I, BERT L. Mrnns, a citizen of the United States, reslding at Jackson, in the county of Jackson, State of Michigan, have invented certain new and useful Improvements in Stock-Feeding Tank Heaters, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

This invention relates to water heaters, and more particularly to a device for heating the water in a stock feed ng tank.

The principal object of this invention is to provide a compactly arranged heater capable of being immersed in the water of the stock feeding tank for maintaining the water at the proper temperature for the stock.

A further object of this invention is to provide a compact heater in which the heating surface is constructed and arranged to produce a maximum amount of heat units to the water in the tank. I

A further object of this invention is to construct a water chamber in the heater so that there will be a supply of water therein even though the supply of water 1n the stock feeding tank becomes depleted.

Still another aim of this invention is to provide a heater of the character described, constructed and arranged so that the fresh air supply to the heater traverses the heater discharge so that the incoming an is heated on its way to the burner, which arrangement in addition, prevents the extinguishing of the burner due to a direct flow of air thereto. p

An additional feature of th1s -1nvent1on resides in arranging the heater so thatthe burner may be readily inserted at the base of the water chamber.

These and other objects will, in part be obvious and will in part be hereinafter more fully disclosed.

Refer ring more particularly to the accompanying drawings: L

'Figure 1 illustrates a perspective view of the stock feeding tank with the heater shown in dotted-lines;

Fig. 2 is a side eleva in section, and

Figs. 3', 4c and 5 are detail views of the ion thereof partly I inner constructionnof theheater showing the intermediate water chamberfthe'upper and 1 lower chimneys, andthe freshpair conduit,

the passage of the air through the heater being indicated by the arrows.

In general, the invention comprises a compactly arranged heater adapted to be immersed in the water of the stock feeding tank. The heater comprises an outer watertight casing formed interiorly with a central water chamber, a lower chimney. provided with a suitable burner, which chimney preferably is formed to project upwardly into the base of the water chamber and is there provided with suitable branch heating conduits passing'through. the water and discharging into the upper chimney which in turn discharges to the atmosphere outside of the tank. The heating conduits in the water chamber are especially constructed to produce a maximum heating effect. The water in the heating chamber communicates with thewater in the stock feeding tank by means of an aperture arranged in the upper wall of the heating chamber, the water circulat ing between the outer tank and the water chamber in the heater by means .of convection through this opening. A fresh supply of air is conveyed to the heater by means of an air inlet located at the upper end ofthe heater so that the entering air passes through and in direct contact with the heated air being discharged fromthe upper chimney. This heated fresh air thence passes down to the .under side of the burner through a lateral conduit in the heater. By

this means, the air is given initial heating as it passes into the heater, and furthermore,

this construction precludes the possibility of the burner from being extinguished, as it might be if the atmospheric air had direct access to the burner. 1

Referring more particularly to the accompanying drawings, the stock feeding tank 1 which may be of any desired shape and size, is provided with a suitable opening here shown as a depending flanged mouth,

by means of which the cattle have access to the water within the tank. The water level line as shown in the drawings is indicated at 3. This tank opening may be closed by any type of hinged door 4.

For the purpose of keeping the water in the tank from congealing and for maintain ing it at the proper temperature for stock ffeeding purposes, there is provided a novel "form of heater. In the present instance, this heater comprises an outer casing 5 of metal or'any suitable material and preferably cy- This opening is arranged at the 30 plurality of one or more lindrical in shape, flanged at its upper end as at 6 to provide a shoulder surrounding the opening 7 in the upper face of the tank 1, by which the heater depends into the tank and is immersed in the water therein. Obviously any desirable manner of submerging the desired portion of the heater and holding it in proper position in relation to the walls of the tank may be availed of.

In order to provide a heating device which combines a minimum amount of heating surface with a maximum amount of heat units produced, the heater is provided with a relatively small intermediate water chamber 8 formed by upper and lower partition walls 9 and 10 which extend across the width of the heater, and by a vertical wallll which is spaced from the back wall 12 of the heater to provide an air passageway hereinafter referred to. In this manner, the interme diate front portion of the heater is partitioned off to form a water chamber of relatively small capacity as compared with the whole contents ofthe heater.

For the purpose of forming communication between this water chamber and the water in the stock feeding tank to be heated, there is provided one or more openings 11.

upper portion of the heater so that in the event the water level in the outside tank falls below the lower edge of the opening, a sufficient supply of water will remain in the water chamber to prevent the heater from being burnt out by the burner hereinafter referred to. For instance, if an opening were at the base of the water chamber, when the water supply in the surrounding tank became depleted, the water would runout of the water chamber and the heat from the burner would soon destroy the heater.

In order to heat the water in the tank,

there, is arranged immediately below the I a lower chimney 13 which in water chamber the present instance, 13 formed in the shape of a relatively large heating cylinder orconduit, projecting upwardly into the water chamber and making watertight connection with the lower wall 10 thereof. This tube isprovided in any suitable manner with a branch heating conduits of relatively small In the preferred the drawings, this suitable number of apertures 1a to which are. permanently connected the heating tubes 15 which extend trally arranged upper chimney 18 opening directly the upper end of the casing 1 In. inserting the .ings 27 passes through on a diameter so that i the maximum heating eifeet is imparted to the water in the tank. construction as shown in cylinderis formed with a 9. This heating drum in turn discharges through a preferably cen time,

but directly opposite a discharge nozzle 19 terminating outside of the tank, to permit the heated air from the conduit 18 to pass freely into the upper portion of the heater casing 1, and also into the space between the top wall 7 of the large tank and the water therein. The wall 5 of the casing 1 is apertured as at 30. .r-is shown in the drawings, the nozzle is provided with any suitable type of cover 20 which permits the escape of the heat and gases and prevents the direct entrance of atmospheric air down the nozzle 19. The usual damper 21 for controlling this outlet is provided. In order to provide additional heating surface, the lower chimney 13 is formed with a water heating tube 22 extending transversely across the chimney and arranged immediately over the flame of the burner.

Any desired source of heat may be used,

but in the present instance, the ordinary type of kerosene lamp is shown. This lamp is located in the base of the heater under the lower'chimney 13 so that the heat therefrom passes directly up the hollow cylinder 13 as shown by arrows in Fig. 4:. In order to preventthe flame from being extinguished, the lower chimney 13 depends well below the burner, but is cut away as at 23 in order to permit the burner to be inserted and withdrawn. If desired, any type of hinged door may be provided at this point. The burner is inserted into the heater by means. of a hinged door 24 located on the upper face of the heater mica-faced opening reflection from the means of a second directly mica door 25 located in the lower tube 13.

burner, the door 24 is pivoted on its hinge 26- and the burner passed down the side of the heater and placed in position.

In order to provide a source of fresh air supply for the burner, and in order to prevent this inrush of air from extinguishing the flame, the heater is provided with air .inlet openings 27 arrangedin the sides of the door 24. The air entering these open-. perforated plate which is a part of said door, and thence passes into the casing 1, where it passes through the heated air discharging from the conduit 18. The fresh air thence passes around the centrally disposed upper chimney 18, whence it passesfldown the fresh air conduit 29'to the base of the burner, establishing a circulation up through the lower chimney 13, the branch heating tubes 15, out through the heating drum, the up per chimney 18, and the discharge nozzle 19, into the atmosphere, all of which is indicated by the arrows in Fig. 4. At the same into thelateral fresh: air passage 29 and a portion of the heated. air will pass the atmosphere, a

likewise into the spaces 31 above the heating drum 9, and thence through the passage out into the large tank to heat the surface of the water.

It is obvious that a heater constructed as above, provides a very compact and small heating unit capable of being inserted and immersed in a stock feeding tank. It is further obvious that by the peculiar arrangement of heating conduits, and particularly by the arrangement of the cross heating tube 22, by the water in the water chamber 8 will be very quickly heated, and will be carried by convection upward through the opening 11 into the surrounding tank, which will result in an equal flow inwardly through the opening ll of the cooler water of the tank.

It will also be clear from this disclosure that the invention is not restricted to the exact form and arrangement of the water chamber, the upper and lower chimneys, nor of the arrangement and configuration of the branch heating conduits, since these features may be altered in any desirable way within the scope of the invention as set forth in the ap ended claims.
